1. Tie the fresh crabs with ropes and rinse them with clean water.

2. Crabs are placed in the cold storage layer of the refrigerator, which is a temperature environment of about 4 degrees above zero, and crabs can sleep in this environment.

3. Put the crab in and cover it with a wet towel to keep it moist and breathable. Don't get too close, lest the ventilation be poor, and the crab will suffocate and die.

Crabs can only be stored for two or three days and should be eaten as soon as possible.
